2) This helps the get up to temperature quicker and more consistently in colder climates, this is NOT my daily driver so this does not concern me in the slightest. It might get a cold start maybe 1-2 times per year.

Not talking about FITV, Im just talking about IACV

Thats just BS, since you can just bypass/block FITV and relocate & keep using IACV like with Skunk2 manifold
